Answer:
The answer to your question is: 40.8 g of NaN₃
Step-by-step explanation:
NaN₃ mass = ?
nitrogen = 1.2 moles
Equation
2NaN₃ ⇒ 2Na + 3N2
2 moles of NaN₃ ----------------- 3 moles of N₂
x ------------------ 1.2 moles of N₂
x = (1.2 x 2) / 3
x = 2.4/ 3
x = 0.8 moles of NaN₃
MW NaN₃ = 23 + 28
= 51 g
51 g of NaN₃ ----------------- 1 mol
x ----------------- 0.8 mol
x = (0.8 x 51) / 1
x = 40.8 g of NaN₃
Answer:
84 cm cubed
Step-by-step explanation:
length is 4 and width is 7 and the height is 3 so it is 4*3*7 which is equal to 84
Answer:
f(x)=50x
Step-by-step explanation:
f(x)= y
y= 50
if x is 1 the answer is 50
if x is 2 the answer is 100
The numbers will just keep getting higher depending on the x value
40/3 days, (13.33 days)
Step-by-step explanation:
Set up the equation, 15/20 = 10/x, and then use cross mutiply to solve it.
10 * 20 = 15x, x = 200/15 = 40/3
Why?
b/c if each pig eats the same amount of food, then the ratio between the number of pigs and days should remain constant.
Answer:
Step-by-step explanation:
Multiply both sides by 2
2x=3y+6
Move variable to the left-hand side and change its sing
-3y=6-2x
Divide both sides of the equation by -3
